Calibrate Using an External Calibrator (
E-
C
al
)
If
E-
C
AL
(External Calibration) was selected above in
Select Calibration
Method, the meter must be calibrated with an external calibrator.
Desired values can be programmed using the
Five Basic Digit/Display-
setting Instructions described on page 19. See Figure 13: Two-point
External Calibration Flow Chart on page 18.

appears push
ENTER
again.
2.
InPt 1
flashes. Apply input 1 signal (e.g. 4mA, 1V, etc.) then push
ENTER,
Program desired display for input 1.
3.
InPt 2
flashes. Apply input 2 signal (e.g. 20 mA, 10 V, etc.) then
push
ENTER
. Program desired display for input 2.
Calibration Error (
Error
)
A meter display of
Error
during calibration indicates that the
calibration process was not successful and the meter needs to be
recalibrated.
1. The
Error
message will appear if input 1 signal and input 2 signal
are too close together, see Table 2 on page 22.
2. The
Error
message will appear if input 1 signal is inadvertently
also applied for input 2 calibration, or
ENTER
is pushed before
applying input 2.
Programming Confirmation
The values that have been programmed can be quickly checked to
make sure they are the desired values. To do this, apply the desired
signal for each point and check the display.

General Calibration/Scaling Instructions
Calibration is performed from the front panel using the
ENTER
but-
ton. It does not require any tools or disassembly of the meter. A
calibrated signal source is required if external calibration (
E-
C
AL
) is
selected.
For best results, allow meter to warm up for at least 30 minutes.
The calibration input signals must be within the range of the meter
and input 2 must be greater than input 1. (However, display for input
2 does not have to be greater than desired display for input 1.)
An
Error
message will appear if input 1 signal and input 2 signal are
too close together:

)
If
I-
C
AL
(Internal Calibration) was selected above in
Select Calibration
Method, the meter can be scaled without applying an input. Desired
values can be programmed using the
Five Basic Digit/Display-setting
Instructions described on page 19. See Figure 13: Two-point External
Calibration Flow Chart on page 18.
